Benzalkonium Chloride in Commercial Grapefruit Seed Extracts

[Jimi Stein]

Finally the riddle is getting solved with the help of John

Wel I was reporting some time ago that grape fruit extract was successful against bad breath because of the chemicals that is has not because of grapefruit. And finally we can see why. GSE uses Benzalkonium Chloride in its ingredients.

AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

GSE is a bunch of crap!!!!!!!!!!!

Abstract:

Commercial grapefruit seed extracts (GSE) were extracted with chloroform. The solvent was evaporated, and the resulting solid was subsequently analyzed by high-performance liquid chromatography (HPLC), electrospray ionization mass spectrometry (ESI/MS), tandem mass spectrometry (ESI/MS/MS), and elemental analysis (by proton-induced X-ray emission analysis). Three major constituents were observed by HPLC and were identified as benzyldimethyldodecylammonium chloride, benzyldimethyltetradecylammonium chloride, and benzyldimethylhexadecylammonium chloride. This mixture of homologues is commonly known as benzalkonium chloride, a widely used synthetic antimicrobial ingredient used in cleaning and disinfection agents.

Keywords: Benzalkonium chloride; grapefruit seed extract; electrospray ionization mass spectrometry; proton-induced X-ray emission (PIXE) analysis; antimicrobial activity

Awesome finding, Jimi. I knew these companies that make "cure" products are a bunch of scumbags, ripp offs. They make all kinds of BS claims, all along it was the active chemical Benzalkonium Chloride that killed the bacteria and not grape fruit seed extract (GSE).
